Determining the effectiveness of cinnamon oil as a natural insect repellent

Observation

It was observed that most of the insects avoided the cinnamon coated banana. The few that went towards the cinnamon coated banana only spent a short time on its surface. Instead, majority of the insects were attracted to the untreated banana, and either stayed on the surface of the untreated banana or remained in its vicinity.

It was also observed that there were some insects that stayed on the wall of the tank instead of either half of the bananas.
